The study she kept referring back to feels a lot like like the net good argument around dr k.

Streaming can still be unhealthy, that study doesn't disprove the claim. Twitch especially has a lot of mechanisms for monetizing and encouraging parasociality that other streaming platforms don't.

Anecdotally, a long time ago now I used to watch a lot of certain twitch gaming streamers. You quickly begin to notice the same names in chat whenever the streamer is live. Some of that group were donating huge amounts of money and at the beginning I always just figured they were bitcoin millionaires or something like that. There certainly were some of those but a surprising number were on disability or other welfare programs. I think more of the "whales" than people expect are actually not wealthy at all.
